Supporting Information

Supporting Information File 1: Detachment of a surface with a small gradient in the local coefficients of friction.
Time evolution of the dimensionless longitudinal stress σx/p for a surface with a gradient in the local coefficients of friction, computed using SBM for the case Δ = 0.1. The detachment process starts where the local static friction threshold is smaller, i.e., where the local static coefficient of friction is smaller.

Supporting Information File 2: Detachment of a surface with a large gradient in the local coefficients of friction.
Time evolution of the dimensionless longitudinal stress σx/p for a material with a gradient in the local coefficients of friction, computed using SBM for the case Δ = 0.3. The detachment process starts where the local static friction threshold is smaller, i.e., where the local static coefficient of friction is smaller.

Supporting Information File 3: Detachment of a surface with a positive triangular gradient in the material Young’s modulus.
Time evolution of the dimensionless longitudinal stress σx/p for a material with a triangular gradient in the Young’s modulus, computed using SBM for the case Δ = 0.2. The detachment process starts at the centre of the sliding plate and propagates towards the edges.
Format: AVI Size: 5.7 MB Download
Supporting Information File 4: Detachment of a surface with a negative triangular gradient in the material Young’s modulus.
Time evolution of the dimensionless longitudinal stress σx/p for a material with a negative triangular gradient in the Young’s modulus, computed using SBM for the case Δ = −0.2. The detachment process starts at the edges of the sliding plate and propagates towards the centre.

Supporting Information File 5: Effect of the finite-element type on the surface stress distributions.
Normalised normal and tangential stresses with respect to the applied pressure p as a function of the dimensionless coordinate x/L. C3D8R: 8-node brick with reduced integration, C3D8I: 8-node brick with 8 points of integration and incompatible modes.

Supporting Information File 6: Computed values of the global static coefficients of friction.
Tables reporting the computed absolute values of the global static coefficients of friction µs, as function of Δ, obtained using SBM and FEM, for the case of a gradient in the local coefficients of friction and a gradient in the material Young’s modulus.
